Hidden Cortana gems

Perhaps this is common knowledge but I thought I would post here in case it is unknown to others

I recently read that Cortana can be activated over in-car bluetooth by dialing (555) 555-9876. I added that number to my Tundra and it worked. a Little clunky “Dial by name”, “Cortana”, but much safer than fumbling with the phone.

I have wanted something like this for a long time – only accidently stumbled across it while reading other articles. Nice feature

I didn't know that. "Hey Cortana" works, when the car mic can hear well enough from amidst the ambient noise. I still have a hard time waiting for the tonal prompts while Cortana prepares to listen to a question it just asked. I start responding, only to hear the tone which Cortana uses to indicate it has begun listening, so I stop mid-response and start again and it tends to be a mash-up of mixe-up confusion.
